Technical Examples
  1. To identify a failed atmospheric pressure sensor in a control apparatus having two atmospheric pressure detecting systems as a failsafe. A first comparing unit outputs an abnormal signal when a difference between atmospheric pressures detected by two sensors is larger than a threshold value. An atmospheric pressure estimating unit estimates the atmospheric pressure from an engine revolution, a throttle opening, and a manifold pressure. The difference calculating unit calculates a difference between the detected atmospheric pressure and the estimated atmospheric pressure. The difference calculating unit calculates a difference between the detected atmospheric pressure and the estimated atmospheric pressure. When an abnormal signal is outputted from the first comparing unit, a second comparing unit compares the differences in response thereto. The failed atmospheric pressure sensor is identified according to which one of the differences is larger.
